PROFIBUS/PROFINET implementation
PROFIBUS/PROFINET is implemented on the communication modules strictly in
accordance with standard IEC 61784-1:2002 Ed1 CP 3/1. Cyclic data communication
(standard specified by EN 50170) and optional non-cyclic data communication are used.
The following figure shows the communication interface to a communications module. PQW
and PIW are exchanged cyclically between the CM and function block. PIW informs the
function block when commands and data may be transferred to the communications module.
Commands and data are put into data records.
